I am wondering what exactly they did to my car when it was shipped to the US from Germany. I know they changed the headlights and put on the different speedo face and put some beams in the doors, but I am most concerned about my engine. Does anyone know exactly what was done to my engine? Or does anyone know where I can find this out?
